Specification of Letters Patent.

Application filed February 15, 1908.

Patented July 21, 1908.

Serial No. 416,056.

To all whom it may concern:

Be it known that I, AUGUST M. H. DE BRUYOKER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Ventilator, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved ventilator, more especially designed for use on chimneys, and arranged to insure a proper draft at all times by causing a suction in the chimney, irrespective of the wind blowing up or down in the ventilator.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings.

forming a part of this specification, in which similar characters of reference indicate correspondingparts in both views.

Figure 1 is a sectional side elevation of the improvement; and Fig. 2 is a like view of a modified form of the same.

The chimney pipe A is surrounded at its upper end by a deflector B of inverted frustoconical shape, the base of the deflector B lying in a horizontal plane passing through the upper end of the chimney pipe A, so that the deflector B forms with the terminal of the pipe A a pocket C. Centrally above the pipe A and its deflector B is arranged a conical cover D, supported with its base a distance above the top of the pipe A and the deflector B, by the use of braces E attached to the upper end of the chimney pipe A. By reference to the drawings, it will be seen that the base of the conical cover D is approximately the same size as that of the base or upper end of the deflector B, and hence an annular passage is formed between the base of the cover D and the upper ends of the chimney pipe A and the deflector B, for the escape of the smoke and gases rising in the chimney pipe A. The chimney pipe A, the deflector B and the cover D are inc osed in a shell or a mantle F, shown in Fig. 1 as formed of the upper and lower parts F and F both of frusto-conical shape and having their bases united approximately opposite the upper end of the deflector B. The apex of the cover D terminates approximately at the top of the upper section F of the mantle F, and the base of the cover D is spaced from the wall of the upper section F a distance correspond.- ing approximately to that of the space between the lower end of the section F and the chimney pipe A.

Now by the arrangement described annular assages are formed between the mantle F, t e pipe A, deflector B and cover D, in such a manner that air entering the shell or mantle F either from the top or from the bottom causes a suction in the pipe A, to insure proper draft in the chimney pipe and with out danger of the wind, blowing either up or down in the mantle F, from passing into the chimney pipe A. It is understood that the wind blowing downward in the mantle F is deflected by the cover D into the lower section F of the mantle, and any portion of the wind that may accidentally reach over into the space between the cover D and the deflector B is caught in the pocket C and hence does not pass into the chimney pipe A. Wind entering the lower end of the shell F and blowing in an upward direction is deflected by the deflector B into the space between the upper shell section F and the cover D, to finally ass out through the upper end of the section li". The upper shell section F is preferably connected by braces G with the cover D, and stays Gr connect the lower shell section F with the chimney pipe A. A conical hood H is supported above the shell F by the use of suitable braces I attached to the upper shell section F, and this hood H has its base spaced from the top of the section F, and the diameter of the base is in excess of that of the up er end of the section F.

n the modified form illustrated in Fig. 2 the chimney pipe A, the deflector B, the pocket C, the cover D and the braces E are the same as above described in reference to Fig. l, and the shell or mantle J is provided with the sections J, J of frusto-conical shape, united at their bases, located approximately opposite the middle portion of i the passage or space between the base of the cover D and the upper end of the deflector B. The shell sections J and J 2 terminate in cylindrical portions J J, of which the portion J supports a hood H by suitable braces I, and the portion J is connected by stays G with the chimney pipe A. In this case the action is approximately the same as the one described above in reference to' Fig. 1, that is, wind entering the shell J at the top and moving downwardly is not liable to pass out danger of the wind entering the chimney pipe and blowing down the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1; A ventilator, comprising a central pipe, adeflector surrounding the said pipe at its upper end and forming a pocket with the same, a conical cover arranged above the said pipe and its pocket, a shell inclosing the said pipe, deflector and cover, the shell having two frusto-conical parts united at their bases, and having their sides spaced from the said cover and the said deflector to form annular passages for the wind and smoke, the apex of the said cover terminatingiapproximately in line with the top edge of the upper part of said shell, and an outer hood of conical shape arranged above the upper shell part.

2. A ventilator, comprising a central pipe for the passage of the smoke and gases, a deflector attached to the upper end of the said pipe and of inverted frusto-conical shape, the base of the deflector being flush with the upper end of the said pipe, a conical cover cen trally suspended above the said pipe and its deflector, the base of the cover being approximately of the size of the base of the deflector, a shell surrounding the said pipe, de-

flector and cover, the shell being formed of two frusto-conical parts united at their bases, the latter lying in a horizontal plane containing the upper ends of the said deflector and pipe, the apex of the said cover terminating approximately at the top of the upper section of said shell, and a conical hood supported above the top of the shell, the base of the hood being spaced from the top of the upper section of the shell and the diameter of said base being in excess of the top inlet of the shell.

3. A ventilator comprising a central pipe, a deflector surrounding the said pipe at its upper end and forming a pocket with the same, a conical cover arranged above the said pipe and its pocket, a shell inclosing the said pipe, deflector, and cover and spaced therefrom, the said shell being open at both ends, the apex of the said cover terminating in line with the upper edge of said shell, and a hood of conical shape supported above the top of the shell.

4. A ventilator comprising a central pipe, a deflector surrounding the said pipe at its upper end, a conical cover arranged above the said pipe and deflector, a shell open at both ends and inclosing the said pipe, deflector and cover, the shell having two frustoconical parts united at their bases and having their sides spaced from the said cover and the said deflector, the apex of the said cover terminating in line with the upper edge of the upper part of the shell, ahood of conical shape above the upper shell part and connected by braces thereto, braces connecting the lower shell part with said central pipe, and braces connecting the said conical cover with the upper part of said central pipe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
